321576 ÷ 91 
Our goal is to divide 321576 by 91.

Step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 91

Going ahead to step 2:
When dividing 32 by 91, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 91

On to step 3:
When dividing 321 by 91, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 48 after subtracting 273 from 321.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 91

Going ahead to step 4:
91 goes into 485 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 455 from 485 and we're left with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 91

Advancing to step 5:
The number 91 fits into 307 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 353.0
If we subtract 273 from 307, we get 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 91

Advancing to step 6:
When dividing 346 by 91, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3533.0
If we take 273 away from 346, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
730 divided by 91 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3533.8
Deduct 728 from 730 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 91 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3533.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 91, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 3533.802
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
91 goes into 180 1 times with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 3533.8021
The remainder is 89 after subtracting 91 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
The number 91 fits into 890 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 3533.80219
Subtract 819 from 890 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 12:
91 can be fit into 710 7 times, resulting in a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 3533.802197
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
730 divided by 91 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3533.8021978
Subtract 728 from 730 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
91 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3533.8021978
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 3533.8021978, with a leftover of 2e-08.
